Are you one of those people that loves cracking their knuckles? If you are, you have probably heard over and over again that you shouldn’t because it is bad for you and will lead to arthritis or non functional hands. This idea that cracking your knuckles is bad for you actually may not be true at all!
The people over at Vox have created this informative video which may give you a little more insight into what you once thought was a guilty pleasure. This video seeks to educate you on what is really going on when you crack your knuckles.
Inside each of your knuckles is a liquid called synovial fluid. This liquid lubricates your joints and keeps them working properly. When you crack your knuckles, that popping sound is gas bubbles inside the synovial fluid collapsing. This is different then the popping sound you hear in your knees if you get up too fast, which is your tendons rubbing over your bones and muscle.
One man decided that he would test the theory, that cracking your knuckles causes arthritis. For sixty years he cracked his knuckles in one hand and not in the other. The good news for us knuckle crackers is that neither hand showed more arthritis than the other. This finding is great news for those of us who are addicted to that pleasurable pop. Do you crack your knuckles?
